The Campeonato Anual Regional del Oeste, commonly known as the Torneo Cuyano or Torneo del Oeste, is a regional rugby union competition in Argentina.
The competition started in 2000 and involves clubs from the unions of Cuyo, San Luis and San Juan.
This annual tournament has traditionally been dominated by Mendoza (Cuyo) clubs. As in other inter-provincial tournaments, such as the Torneo del Litoral or Torneo del Noroeste, the best clubs from the Torneo del Oeste qualify for the national level Torneo del Interior.
The Torneo del Oeste includes 10 teams competing for the provincial title. All the champions are listed below:
